We look at the division of 374572 by 83 
The aim is to understand the frequency of 83 in 374572.

Going ahead to step 1:
3 divided by 83 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 83

Moving on to step 2:
If we divide 37 by 83, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 83

Let's proceed to step 3:
When dividing 374 by 83, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 332 from 374, we get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 83

Step 4:
83 goes into 425 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 415 from 425, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 83

Going ahead to step 5:
83 goes into 107 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 451.0
Subtract 83 from 107 to get 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 83

On to step 6:
When dividing 242 by 83, we get 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 4512.0
Deduct 166 from 242 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
83 can be fit into 760 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 4512.9
If we subtract 747 from 760, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
83 can be fit into 130 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 4512.91
Deduct 83 from 130 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
The number 83 fits into 470 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4512.915
If we take 415 away from 470, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
83 can be fit into 550 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 4512.9156
Subtracting 498 from 550 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
83 can be fit into 520 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 4512.91566
Subtract 498 from 520 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 4512.91566, and the remainder is 2.2e-05.
